What is the main benefit of a twin-plate clutch over a single-plate clutch?

A twin-plate clutch has two friction surfaces instead of one, which greatly increases the total surface area. This allows for better heat dissipation and the ability to handle significantly more torque without slipping, making it ideal for high-performance applications.

Does this clutch kit include everything needed for installation?

This kit includes the twin clutch discs, pressure plates, and the soft diaphragm release bearing. It is recommended to consult the manufacturer's installation guide for a complete list of required components and tools, as some additional items may be necessary for a proper installation.

How does the 'soft diaphragm' release bearing affect the clutch pedal feel?

The soft diaphragm release bearing is designed to provide a more comfortable and less stiff pedal feel compared to some other high-performance twin-plate clutch setups. This makes the clutch easier to operate during daily driving while still maintaining the performance capabilities of the twin-plate system.

Product Details

What you get with this OS Giken STR Series Twin Plate Clutch Kit is a complete package designed to handle the demands of your 2004-2011 Mazda RX-8. This kit includes the twin clutch discs, pressure plates, and the soft diaphragm release bearing, all engineered to work together seamlessly. It's a substantial upgrade for RX-8 owners looking for a clutch that can handle more power and provide a more direct feel than the stock unit.

The STR Series clutch from OS Giken is known for its robust construction and ability to manage higher torque loads, making it a popular choice for modified rotary engines. The twin-plate design significantly increases the surface area compared to a single-plate clutch, which helps dissipate heat more effectively and reduces the likelihood of clutch slip under aggressive driving or when adding performance modifications. The soft diaphragm release bearing is a key component here; it's designed to offer a more comfortable pedal feel than some other high-performance twin-plate clutches, making daily driving more manageable without sacrificing performance when you need it.

Installing a twin-plate clutch is a more involved process than a standard clutch replacement, often requiring specialized tools and careful attention to alignment. However, the benefits in terms of durability and performance are substantial for RX-8s that are pushed hard or modified. This OS Giken kit is a well-built solution for those seeking to maximize their RX-8's drivetrain capability and ensure reliable clutch operation under demanding conditions.
